What is making you weary? Is it your job? Is it your family? Is it your finances? Whatever it is, it needs to be relinquished. Carrying that heavy burden on your back is not doing anyone any good, and it is especially harmful to you.
Maybe you are stressed. Maybe you always have to be in control, and your circumstances are showing you how little control you really have. Maybe you carry the weight of the world on your shoulders. Maybe, every time you talk to one of the kids in your ministry, their problems and burdens only add to your own pile that is surely to overwhelm you at any moment. Take heart. Help is on the way.
